MetalRoof CoatingSystems
Metal roofs fail at seams, fasteners, and panel laps. Not at the metal itself. Silicone coating seals every fastener head, bridges every seam, and stops rust migration without removing a single panel. Restore at 50–75% less than full replacement with a manufacturer-backed warranty to 30 years.

What we can
restore.
If your deck substrate is listed, this service is a candidate. If it's not — or if moisture content exceeds 30% by volume — we'll tell you that too.
No surprises.
No pressure.
Just documented work.
Every seam, fastener, panel transition, and penetration is inspected. Thermal imaging identifies moisture intrusion beneath the metal. Panel structural integrity confirmed.
Active rust treated with rust-inhibiting primer. Panels power-washed, all fastener heads sealed, and critical seams reinforced with fabric-embedded silicone.
Silicone coating spray-applied over the entire metal substrate, bridging panel transitions, seams, and fastener patterns into a continuous watertight membrane.
Post-installation inspection confirms complete coverage. Manufacturer warranty issued for 10, 20, or 30 years. System recoatable indefinitely.

Per-square-foot pricing for Metal Roof Coating. Compared side by side with full-replacement baselines from 200+ projects.
New metal roof installation runs $15–30/sq ft. Silicone coating delivers equivalent waterproofing at $3–6/sq ft — saving 70–80% on day-one cost.

about this service.
Pulled verbatim from assessment calls on this specific service.
01What causes most commercial metal roof leaks?
Most metal roof leaks originate at fastener heads, panel seam laps, and flashing transitions — not the metal panels themselves.
02Does silicone coating handle metal roof thermal expansion?
Yes. Silicone maintains elasticity from −65°F to 300°F, which covers the thermal expansion range of steel and aluminum panel systems across all U.S. climates. Acrylic and urethane coatings lose flexibility at temperature extremes and crack at seam transitions. Silicone does not.
03Can you coat a metal roof with active rust?
We treat active surface rust with rust-inhibiting primer before silicone application. Structural rust that has compromised panel integrity is different — that requires panel replacement, which our assessment identifies clearly. Surface corrosion at fastener heads and seam laps is standard prep, not a disqualifier.
04What metal roof profiles do you coat?
Standing seam, R-panel, corrugated, barrel vault, and Galvalume are all within our scope. Each profile has different seam geometry, fastener patterns, and thermal movement characteristics that affect prep scope. Barrel vault and curved profiles require additional attention at panel transitions. We inspect first and document the full scope in writing before any work begins.
05Does metal roof coating qualify for Section 179 tax deduction?
Yes. The IRS classifies roof coating as a repair expense, not a capital improvement, making it eligible for immediate Section 179 deduction rather than 39-year depreciation. On a large facility, the year-one tax difference between coating and replacement can be substantial. We provide CPA-ready documentation.
